Zoom Q8 Camera shows Full 4 hour video on camera but only hour on SD Card display on Lenovo

Hey, I mostly use the Q8 for music captures but sometimes I use it for addtitional security for the house when I am at work or something. Today I recorded it for 4 hours while I was out and it shows this full 4 hours on the camera's file display. But when I load it up on the computer, it only shows about 56 minutes. Furthermore, I changed the name of the file to make it easier to find on the laptop and now it only shows the 56 minute version on the computer and not at all on the Q8. In fact, files on there with any other name other than the 'Zoom insert number' they were given automatically are not coming up on the Q8 either (only on the computer). 

Additionally, different issue but at some point OBS (which I use for streaming with the Q8) stopped detecting the video and only displays the audio now. Anyone help with any of these issues? Thanks.
